The EVO Handlebar is ProTaper’s top-of-the-line model without a crossbar. Oversized diameter handlebars, without crossbars, were invented and patented by ProTaper in 1991. This design allows the handlebar to flex more and absorb impacts better than conventional bars, offering the rider more comfort and less fatigue without sacrificing bar strength. The EVO Handlebar utilizes a computer-profiled 4mm wall design and is up to 25 percent lighter than other bars, yet up to 45 percent stronger. According to Motocross Action Magazine, the amount of flex that the EVO provides (takes the jolting edge off of rough tracks and lessens hand fatigue.) Transworld Motocross adds, (We don’t care what kind of bike you ride, the EVO will improve the comfort.)1 1/8 Inch tubing at the clamping areaMade from proprietary 4mm 7000 series aluminium alloy for superior tensile and yield strengthBest balance between fatigue life, impact strength, and impact-absorbing flexHigh-tech, stress-relieved, shot-peened and anodized finish for unmatched durabilityIndependent lab tests show that the EVO Handlebar leads the market in fatigue lifeEpoxy inner coating resists corrosionClutch-side knurling provides maximum grip adhesionChemically applied cut lines and alignment grid are scratch- and peel-resistantPlastic bar end plugs keep the elements out and provide a stronger base for grip endsWeighs only 1.4 lbs.
